hot battery

yerterday, while on a trip by car, i tried to use gps for a while and then some surf on net. then battery temperature was 40-41 celsius. is it dangerous?

Not dangerous. Just a bit hot.

When it's over 120 you should try to settle down your phone. I played 3D games while charging and it gets really hot, but still my phone can manage it.

Converted to celsius: when the battery temperature is over 48°C - 49°C you should try to settle down your phone.

Possible to block hardware throttling?

Often when you over clock, the phone heats up and starts to slow itself down from getting too hot. Is it possible to bypass that?

Which part of TOO HOT is so hard to understand? I'm no ARM CPU expert but heat throttling is usually hard-wired into the CPU. For a good reason.

put your phone in the microwave on high for 30 seconds. This will disable the temp sensor......................

If you haven't seen this yet, you should.
It's a video from a brief period when Intel had reliable thermal throttling, but AMD's wasn't reliable yet:

If you wanna avoid throttling, reduce heat. Could consider picking the phone appart to reapply thermal paste, and or put some extra holes in it for cooling.

SO.... you want your phone to overheat and get damaged?
Good call.

[Q] CPU question

Hey guys! I've been playing a PSP emulator on my note 3 and it runs pretty hot. I was wondering if anyone had any idea of how hot is too hot for the cpu. The battery stays pretty cool so I'm not worried about the battery temp, only the cpu. Thanks in advance!

The cpu's in these things will produce some heat when fully ramped up.

Yes I am aware of that lol My concern is if i should worry about it and what temperatures should I watch out for. Thank you for your reply.

Anything over 100 f I would be concerned about. Enjoy!!!

The phones have a thermal throttle, so you should be fine unless you adjusted the throttle. In that case you should already know what's safe and not. And just an fyi, 100 degrees f is not hot for a cpu. Just when you feel something warm to the touch, that item is already at about 100 degrees f.

Thanks for your replies guys I really appreciate it!

I saw in a forum, 90 degrees for note 3 is still normal

Do you mean 90 C? Because I expect 90F ambient temperature whole summer and the phone has to be at least that much, even when shutdown. Add a little bit sun exposure and it can easily hit 120-130F without doing anything and I'm not talking Death Valley, Phoenix or Vegas, up there with outside temperatures hovering around 110 F or more, unless you don't come out from AC cooled room at all whole summer, the phone will be hot. If I remember correctly my computer CPU would start throttling somewhere around 80C, but my computer's GPU could go close to 100C. I would think phone is similar, except without active cooling, it probably starts to throttle sooner.

I use Battery Monitor Pro, and it keeps track of daily temps for the week. My lowest is 97.2F, and highest is 104.2F. It gets hottest playing games, but nothing so hot that I have to stop. As previously said the phone has a built in throttle. You can even know when it kicks in as the screen will dim a bit even if you don't have automatic brightness on.
EDIT - And by lowest of 97.2F I mean that is the highest for the day it recorded, not the lowest my phone runs at. Sitting idle with the screen off it's around 86F right now. I've seen it as low as 76F.

My droid incredible would hit 118F on a regular basis. My GN3 so far has stayed below 95F. Live in Phoenix, but it it's just now starting to warm up.

My bad, 90F I mean, thanks for correcting, it's like about 32c.

Are you sure about that?

yes, google it

Is Touchwiz DVFS what controls the throttling?

Conditions that made Note 7 burn.

Does anyone knows what conditions the cellphones were at the moment of the combustion? I've read that it had something related to the low battery, but what else? Intense CPU/GPU consume, uptime, heavy use or deep state?

heat ? pressure? no room to expand under heated pressure??

Ain't that easily fixed after some max clock limiter?

Well first of all, you say that it gets too hot? Can you show us a screen shot of how 'hot' it is? It's quite normal that it heats that's just the way how electronics work.. What is your surrounding temperature?

CPU-Z is a good app. Also CPU float to monitor the CPU temp when you are gaming. 40 C is a quite hot surrounding temperature.. Its normal for smartphones to get that hot in such environment. Try to stay out of the sun...

Thats not hot at all... Especially with that surrounding temperature.. Ive hitted 43-45 here while it was 31 degrees celcius.
